Time-based rules

[ignoramous]

Allow users to set time ranges in increments of 30m against each blocklist.

Example:

Blocklist BL1 form 10:30 11:00
Blocklist BL2 from 12:00 23:00
Blocklist BL3 from 22:00 06:00
Blocklist BL7 from 10:30 11:00
and so on...

The stamp generated would be :stamp(map-of-time-ranges-to-blocklists) where map is {time-range -> set-of-blocklists}. For the example above, this would be:

(10:30-11:00) -> [BL1, BL7]
(12:00-23:00) -> [BL2]
(22:00-06:00) -> [BL3]

stamp(map) => stamp(time-slice) + stamp(blocklists)
stamp(blocklists) => existing implementation

---

stamp(time-slice) => base64(dictionary-encoding(time-slice))
dictionary-encoding(time-slice) => {(0, 00:00), (1, 00:30), (2, 01:00), (3, 01: 30), (4, 02:00), (5, 02:30), (6, 03:00),...}
